F.JSIMM0NS. Dressing Milistnes,

Patented Nov. 30, 1869.

N. FErERs, PHOTO-LITHOGRAPNER, wAsHmGT on its under side, and near its circumference, or against a bevel-friction surface in lieu thereof, accordingly as YV is a cog-pinion or a friction-pulley, so that when motion is imparted tothe shaft B through pulley H, and is transmitted, by means of pulleys I and J, to shaft K, and from the latter, through gears X and Y, to shaft V, the platform O, with the stone G upon it, is rotated, through the agency of W, in reverse direction to the rotation of shaft B and stone F, which is carried by it either at a faster or slower rate, according to the size of' the intermediate gearing that gives it motion.

In order to furnish a continuons supply of water, to keep the stones cool, and to wet the sand or other substance that is used to quicken the operation of reduction, I x av sort of duplex funnel on the arm L, in such manner as to envelop the shaft B for a short space above said arm. K

The water, being conducted by a suitable pipe, is poured, in two continuous streams, on the upper stone F, and thence finds its way over the edges andA through the central orifice in the same, to the sand between this said stone and the under stone G.

l The operation of my invention has been suciently manifested by my description of it, and hence I need only further state that I have demonstrated, by actual experiment, that it fulfils the object designed to be accomplished by it, in the most effective and complete manner, and in a very short period of time, as compared with all other inventions of which I have any knowledge.

`Having thns described my invention,

What l claim, and desire to secure by Letters Patent, is-

1. The shaft B, when provided with the hollow arm L, the bar M, the brackets or clamps N N', and the other necessary appliances connected with it, as herein described, in combination with the shafts K and V, when the latter are provided with 'gears J X Y W, the platform 0 block P, axles e e' e e', and wheels d, when all the parts are constructed, arranged, and operate substantially as herein specified, for the purpose set forth.

2. The above combination, in combination with the frame R, the wheels S, and the curved rails TT', snbstantially as herein described, for the purpose set.

forth.

3. The last above-mentioned combination, iu combination with a frame, A, and any suitable motor for operating the machine, as herein described.
